Abstract
To investigate the effects of different zinc fertilizer application rates on the yield and quality of wheat.Using the wheat cultivar Yangmai 25 as the material,5 treatments with varying zinc sulfate application rates were designed:CK(no zinc fertilizer),T1(1 kg/667 m2),T2(2 kg/667 m2),T3(3 kg/667 m2),and T4(5 kg/667 m2).The wheat yield,quality,and economic benefits under different treatments were measured.The results indicated that the grain yield across all treatments ranged from 306 to 372 kg/667 m2,with the highest yield being recorded in the T2 treatment.Regarding quality,the T1 treatment produced the highest values for several key parameters,including test weight(798.23 g/L),hardness(58.46%),dough stability time(7.12 min),sedimentation value(25.92 mL),wet gluten content(26.14%),protein content(13.95%),extensibility(95.83 mm),extension area(70.04 cm2),and maximum resistance to extension(273.26 B.U.),indicating superior quality.In terms of economic benefit,the net return across treatments ranged from 533.25 to 706.65 yuan/667 m2,with the highest return also being achieved in the T2 treatment.For practical production,an appropriate fertilization method can be selected based on specific industry demands for wheat yield or quality.This study provides a scientific reference for achieving high yield and good quality in wheat production.关键词
